39,011 members, a rulebook that bans almost every tool the members need, and an empty wiki that other sites keep citing anyway.
r/arbitragebetting is the main arbitrage community on Reddit, with 39,011 members and posts every day. It is also one of the more strictly governed betting communities on the platform, and the reasons are worth understanding before you post.
The rules are the story
Most betting communities ban selling picks. This one goes considerably further.
- Referral links, affiliate links and tracking links. All banned. Not restricted, not disclosure-required.
- Paywalled posts. If the content sits behind a payment, it does not go up.
- DM me posts. Banned, which closes the standard workaround for everything above.
- Promotion of any external tool. This is the unusual one. A rules update extended the ban to cover all external tool promotion, including bots.
That last rule creates a genuine tension. Arbitrage at any scale is a software problem. Finding a price discrepancy across dozens of books faster than the market corrects is not something people do by hand, so almost everyone doing this seriously uses a scanner or a bot. And the community will not let you talk about which one.
The reasoning is straightforward once you see it from the moderators’ side. The arbitrage tool market is full of paid subscriptions, and the people best placed to recommend one are the people selling it. Allowing tool discussion would turn the community into a marketplace within weeks. Banning it entirely is blunt, and it is the only version that does not require moderators to guess at motive on every post, which is the same logic behind the anti-touting rules we cover in why you cannot sell picks on Reddit.
The wiki that does not exist
The community has the wiki feature switched on, and it contains nothing beyond configuration pages. There is no arbitrage guide, no tool comparison, no getting-started document.
We mention this because pages elsewhere cite an r/arbitragebetting wiki as a source. If you have seen one referenced, it is not there. The same thing happens with the supposed community sportsbook review wiki, which we looked into in our piece on the r/sportsbook wiki. Neither exists.
What actually gets posted
The community runs a pinned Weekly Other Bets Thread for everything that does not warrant its own post. Beyond that, the recurring subjects are consistent.
Getting limited. The dominant topic. Arbitrage is detectable, books do detect it, and the practical lifespan of an account doing it is a constant discussion. This is the single most useful thing in the community for an ordinary bettor to read, even one with no interest in arbing, because the same detection logic applies to anyone who bets well.
Stake sizing and rounding. Betting the exact arb amount is a signature. Most of the practical advice is about not looking like a robot.
Promo conversion. Turning bonuses and free bets into cash at a known rate, which is closer to matched betting than to true arbitrage.
Withdrawal and account problems. A book that is happy to take the bet is not always as happy to pay it out.
The part that matters if you are not an arber
Everything in that community eventually comes back to limiting, and the lesson generalises.
Books limit accounts based on behaviour, not on whether you are technically arbing. Consistently beating the closing number, taking early lines, betting odd amounts and moving quickly on stale prices all read the same way from the other side of the screen. Plenty of people get limited without ever placing an arb.
Which book you are with changes how quickly that happens. Offshore books generally tolerate more than regulated ones, and limits vary widely between them. We cover the landscape in our guide to sportsbooks that do not limit winners, and our sportsbook rankings flag which ones take real action on major markets.

Questions people ask
What is the arbitrage betting subreddit?
r/arbitragebetting, with 39,011 members and daily activity. It runs a pinned Weekly Other Bets Thread and has unusually strict rules. Do not confuse it with r/sportsarbitrage, which has thirteen members and is effectively an empty name.
Why does r/arbitragebetting ban tool discussion?
A rules update extended its promotion ban to cover all external tools, including bots. The arbitrage tool market is largely paid subscriptions, so the people most motivated to recommend one are the people selling it. A blanket ban avoids moderators having to judge motive on every post.
Does r/arbitragebetting have a wiki?
The feature is enabled but there is no content in it beyond configuration pages. Any page citing an r/arbitragebetting wiki as a source is citing something that does not exist.
Will arbitrage betting get my account limited?
Almost certainly, eventually. Books detect the behaviour patterns rather than the intent, and limiting is the most discussed topic in the community for that reason. The same detection applies to anyone who consistently beats the closing number, whether or not they are arbing.
